When performing a hydrostatic test on a low pressure evaporator to determine the source of suspected air leaks you should use __________.

🔍 Key Concepts

• Hydrostatic testing purpose and why liquid is normally used instead of air • Normal operating pressures and temperatures of a low pressure evaporator • How leaks are usually detected in pressure vessels and heat exchangers when checking for air leaks

💭 Think About

• Ask yourself: during a hydrostatic test, what is the safest and most common test medium used on pressure vessels? • Would you ever want to bring a unit up to full operating pressure and temperature just to look for small leaks, or is there a safer way? • Which choices actually describe a hydrostatic (liquid-based) test, and which describe a pneumatic (air-based) or chemical tracer test?

✅ Before You Answer

• Make sure the method uses a liquid under pressure (that’s what “hydrostatic” means). • Verify whether using air under pressure is recommended or discouraged for leak testing large vessels, from a safety standpoint. • Check which options could realistically show where air is leaking while the system is filled with another medium.
